Answer:
3/4; temperature
Explanation:
When animal are crossed to produce a different hybrid having the features or characteristics of both the two crossed animal, a hybrid offspring is produced. The hybrid offspring have all the qualities and characteristics of the parents.
When a parental cross is done between rabbit with albino rabbit, having genotype cc and with Himalayan phenotype that have a genotype of chch, it results in the production of F1 rabbits having all the Himalayan phenotype.
And if the F1 rabbits are now crossed, three-fourth of the F2 offspring have the Himalayan phenotype. The distinctive fur pattern and the unstable allele of hypomorphic ch is caused by the temperature of the surrounding.
